## Security analysis

### Published attack-surface review

- **Summary:** Importing the public package automatically triggers a remote payload fetch and execution path. The payload may arrive over HTTPS or DNS TXT and is launched detached from a temporary directory.

- **Trigger:** Any require/import of beaver-ui-smart-filter.

- **Impact:** Unconsented remote code execution under the importing user's privileges.

- **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T16:08:53.426Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution.

- **Attack narrative:** The main entrypoint silently requires \_adapter.js. Its immediately invoked async initializer selects an OS payload path, downloads bytes from rotating remote hosts or decodes them from DNS TXT records, writes an executable-looking temporary file, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is automatic at import time and has no package feature justification.

- **Rationale:** The source establishes an import-time staged payload chain ending in detached execution of unauthenticated remote bytes. Lack of npm lifecycle hooks does not mitigate this runtime RCE path.

- **Files touched:** index.js, \_adapter.js

- **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js imports \_adapter.js on every package import., \_adapter.js downloads platform binaries from three workers.dev hosts., \_adapter.js can reconstruct a binary via DNS TXT records under wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-spawned via shell., Execution is silent and guarded only by a short-lived temp marker.

- **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint.

## Public findings

### 1. High: Child Process

- **Confidence:** 85.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-smart-filter@35.1.9/_adapter.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L120: try {
L121: const cp = require("child_process");
L122: if (isWin) {
```

### 2. Medium: Network
- **Category:** Source

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-smart-filter@35.1.9/_adapter.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L4: const crypto = require("crypto");
L5: const https = require("https");
L6: const os = require("os");
...
L45: const MAX_AGE = 20870;
L46: const _l = (...a) => process.stderr.write("");
L47: 
...
L56: const isWin = _p("platform") === "win32";
L57: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L58: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L90: try {
L91: require("dns").resolveTxt(d, (e, rr) => {
L92: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-smart-filter@35.1.9/_adapter.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

Public source snippet (untrusted):

```javascript
Trigger-reachable chain: manifest.main -> index.js -> _adapter.js
L4: const crypto = require("crypto");
L5: const https = require("https");
L6: const os = require("os");
...
L45: const MAX_AGE = 20870;
L46: const _l = (...a) => process.stderr.write("");
L47: 
...
L56: const isWin = _p("platform") === "win32";
L57: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L58: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L90: try {
L91: require("dns").resolveTxt(d, (e, rr) => {
L92: if (e || !rr || !rr.length) return r("");
```

### 7. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** lib/telemetry.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-smart-filter@35.1.9/lib/telemetry.js>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = normalized_sha256
matchedPackage = dolyame-boxy-atom-bnpl-badge@35.2.3
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:35.2.3
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
